[PATCH] DebugInfo: Emit any enum with a referenced enum constant.

[David Blaikie]

Just wrapping my head around Arcanist - bumping this to the mailing list.

(apologies to 'reviewers' for popping this into your inbox instead of your mailing list filters... )

This is just a throwaway patch - something I've written up, but I think it'll be too much work to implement well now.

(oh, and imported entities have the same problem as enums... it'd be nice to have their use tracked precisely too so we could reduce some debug info size)

I haven't done the size analysis to see just how bad this is, perhaps it's acceptable as-is, even without the use tracking, but I rather doubt it.
